The available Arctic BC deposition records are restricted to the Atlantic and North American sectors, for which previous studies suggest considerable spatial differences in trends. Here, we present first long-term BC deposition and radiocarbon-based source apportionment data from Russia using four lake sediment records from western Arctic Russia, a region influenced by BC emissions from oil and gas production. The records consistently indicate increasing BC fluxes between and Backward calculations with the atmospheric transport model FLEXPART show vegan dating tumblr source areas and indicate that modeled BC deposition between and is ams radiocarbon dating method driven by emission trends.
